I believe most of the cons I've experienced at ParenteBeard are not company issues but rather industry issues. Public accounting is tough and it is a lot of hard work. With technology today, it is almost like you're available to your clients 24/7. Also with today's technology, clients expect answers right away. There are a lot of deadlines and really no "offseason" depending on what industries you work in.
These types of things have lead to my one con - which is work/life balance. I jokingly refer to it as my work/work balance. Especially being a father who would be a stay at home Dad in a heartbeat and whose personal values prefer faith and family to a fast track career path, this is very tough. However, ParenteBeard really pushes work/life balance and there is some flexibility in our work. For example, I can make an appointment with my son in the middle of the day and just work extra at night. I believe Senior Management really pushes for work/life balance as it is tough in our line of work and they know the value of it.
